Bullet Proof Diesel, a provider of diesel reliability products, released a new line of EGR coolers featuring the patented H-Core technology. The H-Core technology was developed to resist the common causes of EGR cooler failure. Immediately available applications include the Navistar MaxxForce 9, 10, and DT diesel engines, as well as select Cummins, Ford, and Duramax engine platforms.

Taking EGR technology a step further, Bullet Proof Diesel has engineered a patented, self-accommodating "H-Core" design, which allows for the natural expansion and contraction of cooling tubes inside the EGR cooler. According to the manufacturer, this limits structural failure that can occur at the end of the tubes, rupturing the EGR cooler, rendering it useless, and leading to possible engine component damage. The H-Core construction also increases the surface area of the coolant tubes within the EGR coolers, making them more effective heat exchangers than other tubed designs.

The release of H-Core-equipped EGR coolers marks the continuation of Bullet Proof Diesel’s Commercial line of products, designed to be a solution for fleet managers who experience repeated EGR cooler failure within fleet vehicles. Bullet Proof Diesel aims to provide a permanent EGR cooler solution, in contrast to the stock units, which repeatedly need to be replaced in many cases.  Bullet Proof Diesel is currently seeking input from fleet managers and professionals to help determine which applications to produce next, and encourages those with EGR cooler needs to contact them so new prototypes can be developed.
